| Outline of Final Research Achievements |
Magnetic reconnection produces plasma dynamics in the magnetotail through the conversion of the stored magnetic field energy during substorms. Magnetic reconnection usually forms at radial distance of 20-30 Re in the magnetotail. This study has established its three-dimensional structure and size using the observations with the Geotail spacecraft over 20 years. Magnetic reconnection takes place on a line, not as any set of points. The X line (its spatial size is less than one ion inertial length) forms in the center of the magnetic reconnection site, and it is surrounded with the ion-electron decoupling region with a scale size of 10 ion inertial lengths. The X line itself has its dawn-dusk length of > 6 Re in the duskside of the magnetotail.
